High precision analog signals

This sensor-bearing solution delivers the information needed for sinusoidal or vector control for permanent magnet synchronous motors. The units are customizable to electric motor size and number of pole pairs.

Combined functionality benefits

SKF Rotor Positioning Sensor-Bearing Units integrate sensor function into the bearing – an SKF patented design that allows very precise management of the sensor-bearing unit air gap. The result? The units are insensitive to severe magnetic field disturbances, and can withstand application vibration and continuous temperatures up to 150°C. Other design and performance benefits include:

Compactness

Simplified assembly

Sensing performance unaffected by assembly line mounting tolerances

Improved electric motor efficiency

Optimized system noise

Excellent e-motor torque stability

Improved safety and reliability

Improved energy recovery in braking phases
